Design of pH Meter Based on msp430

Abstract:

The pH meter based on msp430 has designed in this paper, and which can accomplish all kinds of functions, for instance, data collection, data analysis, local control and telecommunication. In order to improve the accuracy of data collection we use dual high impedance differential input circuit. And choose temperature transducer DS18B20 which has a function of automatic temperature compensation to reduce the effects of temperature fluctuation on measurement. So it can achieve accurate determination of the pH value of the material.
